为什么无法在Android中获得Google Map V2?

标签: android google-maps

我正在My Android应用程序中实现Google Map V2。我已经完成了这两个链接中的所有步骤: http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/ http://developer.android.com/google/play-services/setup.html 所以请不要将它们作为答案发送。我已下载Maps API,将其复制到Eclipse Workspace中,将其标记为库,在我的项目中引用它。但没有成功。我仍然得到错误:,有人可以帮助我。感谢apreciate。

以下是Log Cat信息:
